| Sumario: | An exhaustive knowledge of the liver vascular patterns as well as possible anatomical variations is significant in the planning and performance of all liver surgical procedures in order for the vascularity not to be disturbed or not causing necrosis of the liver parenchyma postoperatively. The celiac trunk usually provides three branches; left gastric, splenic and common hepatic arteries. The left and right hepatic arteries generally derive from proper hepatic artery which is a branch of common hepatic artery. To study the incidence of celiac trunk ramification, the branching patterns of the celiac trunk of 23 Thai cadavers (17 males, 6 females) were documented during routine dissection by medical students at the Department of Anatomy, Faculty of Medical Science, Naresuan University, Thailand. The clinically important variations of the celiac trunk were noted. The results showed that all celiac trunks arose from each aortas at the T12 vertebra (17.39%, 4 cases), intervertebral disc between T12 and L1 vertebra (78.26%, 18 cases) and upper 1/3rd of L1 vertebra (4.35%, 1 case). We found 95.65% (22 cases) normal celiac trunk trifurcation; whereas, 4.35% (1 case) was abnormal quadrifurcation of the trunk. The accessory hepatic artery (aHA) was presented as an additional branch of celiac trunk because the conventional pattern of the left and right hepatic arteries was presented. This finding is one of the rare anatomical variations which is reported in available literatures. The awareness of celiac trunk and its stems aberrant is important in procedures such as liver transplant for appropriate vascular ligation and anastomosis. |
